Asynchronous accretion can mimic diverse white dwarf pollutants II: water content

Marc G. Brouwers, Andrew M. Buchan, Amy Bonsor +3

Volatiles, notably water, are key to the habitability of rocky planets. The presence of water in planetary material can be inferred from the atmospheric oxygen abundances of pollut…

Focusing of nonlinear eccentric waves in astrophysical discs. II. Excitation and damping of tightly-wound waves

Elliot M. Lynch

In this paper I develop a nonlinear theory of tightly-wound (highly twisted) eccentric waves in astrophysical discs, based on the averaged Lagrangian method of Whitham. Viscous dis…

Importance of magnetic fields in highly eccentric discs with applications to tidal disruption events

Elliot M. Lynch, Gordon I. Ogilvie

Whether tidal disruption events (TDEs) circularise or accrete directly as a highly eccentric disc is the subject of current research and appears to depend sensitively on the disc t…

Dynamical structure of highly eccentric discs with applications to tidal disruption events

Elliot M. Lynch, Gordon I. Ogilvie

Whether tidal disruption events circularise or accrete directly as highly eccentric discs is the subject of current research and appears to depend sensitively on the disc thermodyn…

Focusing of nonlinear eccentric waves in astrophysical discs

Elliot M. Lynch, Gordon I. Ogilvie

We develop a fully nonlinear approximation to the short-wavelength limit of eccentric waves in astrophysical discs, based on the averaged Lagrangian method of Whitham (1965). In th…

Hamiltonian hydrodynamics of eccentric discs

Gordon I. Ogilvie, Elliot M. Lynch

We show that the ideal hydrodynamics of an eccentric astrophysical disc can be derived from a variational principle. The nonlinear secular theory describes the slow evolution of a…
